Every now and then, the Haiku mailing lists explode with emails about something called the distribution guidelines. The Haiku guys set up a set of guidelines with regards to use of the Haiku trademarks and logos; the "Haiku" name may not be used in the distribution's name, official trademarks and logos must be excluded, but the Haiku icons and artwork may be used. In addition to these cosmetic and trademark issues, the guidelines explain what is needed in order to receive the official "Haiku compatible" logo.

Dan0 does not exist, by the way. Maui was the code name for R5.0, based on Hawaii 5.0. Dano was a character from Hawaii 5.0. The beta version of Maui was called Maui/0. The version of Dano released was called Dano/0. Dano was never called Dan0.
